Pneumatic control valve manufacturers in India

Speciality Valve is amongst the most prominent Pneumatic control valve manufacturers in India, with high-performance, heavy-duty, and dependable valve solutions for businesses that need accuracy and durability. Our pneumatic control valves offer great flow control using compressed air and are thus ideal for automating critical process applications.

Why Are Pneumatic Control Valves Needed?

Pneumatic control valves play a major role in processes where fluid or gas flow should be regulated swiftly and accurately. Pneumatic control valves use compressed air power, which supplies a safe and effective alternative for electric control of dangerous or explosive processes.

Key Parts of Pneumatic Control Valve:

Valve Body: Constructed with cast iron, stainless steel, or carbon steel

Pneumatic Actuator: Converts pressure from air to mechanical movement

Positioner: Supplies accurate valve modulation based on control signals

Plug or Disc: Regulates fluid flow

Control Signal Interface: Wired to the control system of the plant

How Pneumatic Control Valves Work?

The valve is controlled by a control signal, usually from a PLC or DCS system, that regulates air pressure in the actuator. The actuator moves the valve stem proportionally, varying the valve opening to regulate flow rate, pressure, or temperature in the system.
